That is a good looking shield. It looks just like the one I purchase from Happy Trails here in Boise. Mine is not painted though. I think mine was made by a company near Reno.
Your choice of oil should serve you well. During the recent upside down adventure of mine, the engine reved up for at least a half min. while I was trying to extracate myself from under the bike. The TW was inverted and I am sure the oil was not going where the designers had planned. Even though I ended up with another problem, the oil seemed to stay coated where it was supposed to be. When the Yamaha shop finished putting the valve adjustment nut back where it was supposed to be, it ran as good as new.
The added bonus of that oil is that the TW shifts very precisely now and I have not missed a shift in some very trying circumstances.
